What do i divide though im new to this math i know how to divide but how do i divide this
Do you have a graphing calculator? It can solve it for you, if you do I can tell you how =)
Okay. Well it can be solved without one, it just takes more work. One second...
Wrong question Luigi
i updates the link to the right question
You'll use the combinations formula as the numbers do not have to be in a specific order. For each slot, 9 numbers could go there (slot 1 could have 1,2,3,4,5,6,7,8,or9... etc) In your formula, n is the number of things you can choose from, and r is how many you choose. Then you can just substitute and solve =)
Coll Do you have skype so i can talk to you to solve this
No, I don't. I'm sorry =(
Ok for Example 0 i can put a 9 and for 1 i can put a 8?
I can only see the Social Security problem.
So what do you mean by examples 0 and 1?
For that they want me to put for 0,1,2,3,4,5,6,7,8,9 For 0 i put 9 and 1 i put 8 and 2 i put 7?
I don't quite understand, but from what I do get I don't think you're on the right track. All you should need to do is figure out what 'n' and what 'r' is.
my heads about to blow from this question And Would N Be 3?
You know what, I am so sorry but I was wrong. Because each slot can only be occupied by one number, it is actually a permutation. Very sorry! So it is the same process, but the other formula. To find N, how many numbers are available for you to choose from?
i can pick any number for 0-9 for n and r so all i gotta do is 10x9x8x7x6x5x4x3x2x1
which is B
I don't think it's B. You are correct that N is going to be 10, but then you have to also plug it into the formula.
Yes, it will be C. =) Good job!! Sorry I probably wasn't the most helpful
You helped alot!
You would make a great Teacher
Aw thank you! That's actually what I want to be =)
Can i fan you?
Sure! (I don't know what that means exactly as I just joined today, but it sounds good, so thank you!!)
I have one more quuestion but i will start a new question
